2-Amino-5-chlorobenzenesulfonic acid

Description:

2-Amino-5-chlorobenzenesulfonic acid, with the CAS number 133-74-4, is an aromatic sulfonic acid characterized by the presence of an amino group and a chlorine atom on a benzene ring that is also substituted with a sulfonic acid group. This compound typically appears as a white to light yellow crystalline solid and is soluble in water due to the sulfonic acid group, which enhances its polarity. It exhibits acidic properties, primarily due to the sulfonic acid functional group, and can participate in various chemical reactions, including nucleophilic substitutions and coupling reactions. The presence of the amino group allows for further derivatization, making it useful in the synthesis of dyes, pharmaceuticals, and other organic compounds. Additionally, 2-amino-5-chlorobenzenesulfonic acid is known for its role as an intermediate in the production of azo dyes, which are widely used in textiles and other industries. Safety precautions should be taken when handling this compound, as it may pose health risks if ingested or inhaled.
